DEOEASED.

SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 637,885, dated November 28, 1899. Application iled March 2l, 1898. Renewed October 24, 1899. Serial No. 734,680. (No model.)

To a/ZZ whom t may concern,.-

Be it known that we, WILLIAM B. MORRIS and GODFREY L. NORRMAN, citizens of the United States, and residents of Atlanta, in the county of Fulton and State of Georgia, have made a certain new and useful Improvement in Smoke-Consumers; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and toligures of reference marked thereon, which form a part of this specication.

This invention relates to devices for causing a better combustion in furnaces, whereby a greater intensity of heat is obtained and the smoke and other inilamlnable products incidental to combustion are consumed, theobject being such as is usual in this class of invention and the invention consisting of the device hereinafter specied and claimed.

The invention is shown in the accompanying drawings, in which- Figure 1 is a perspective view of the interior of the nre-box of a boiler, the front being removed for the purpose of showing the interior. Fig. 2 is a horizontal section on the line of the lower openings into the fire-box on one side and the upper openings on theother side, the section being on the line 2 2, Fig. l. Figs. 3 and I are vertical sections on lines 3 3 and 4 4, respectively, Fig. 1.

In the gures like reference characters are uniformly employed in the designation of corresponding elenlents of construction.

10 is the boiler, and 11 the side wall of the nre-box.

12 is the grate; 13, the bridge-wall.

Obviously this invention may be applied to any form of furnace, a boiler being shown merely for convenience.

14. is a flue which lies within the side wall 11 of the fire-box and passes just within the inner side of the said Wall into and approximately half-way across the bridge-wall 13,

whence it turns parallel to itself, passing along the bridge-wall 18 and the side wall 1l to a point nearthe front, where it again turns and passes parallel to itself along the side wall l1 and across the bridge-wall 13, opening out above the grate-bars near the top of said bridge-wall into 4a number of openings 15. These openings are placed under the overhanging ledge 16. The heated air in passing around the ledge 16 will produce an eddy and will produce combustion in whatever carboniferous matter passes over the bridge-wall 16 and does produce a perfect combustion.

17 is a iiue like the flue 14 and following it in shape, except that it is inverted, the opening being slightly higher in the wall than that of the iiue 14. and passing downwardly in' parallel convolutions, the last convolution of this iiue to extend below the grate-bars, where openin gs 1S permit the heated air to enter under the grate-bars and pass up through the grate and support combustion in the combustion-chamber proper or fire-box as it is ordinarily called. There may be a multiplicity of these lues, the number being regulated by the size of the furnace, the draft required o1' obtainable, and other circumstances.

It is obvious that the air passing through the wall Il and the bridge-wall 13 by way of theflues 14 and 16 will be heated to a very high temperature, and thus will readily produce complete combustion in the combustionchamber.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

l. In a smoke-consumer, a convoluted flue lying in one side wall and substantially halfway across the bridge-wall of a furnace, said flue opening at one end into the atmosphere, and its other end being extended across the bridge-wall, and opening through a multiplicity of ports into said furnace, for the purpose specified.

2. In a smoke-consumer, a convoluted flue lying in one side wall, and substantially halfway across the bridge-wall of the furnace above the grate-bars, said iiue opening at one end into the atmosphere, and the other end being extended across the bridge-wall and opening through a multiplicity of ports into said furnace for the purpose specified.

3. In a smoke-consumer, two convoluted IOO flues, both lying above the grate-barsin each side wall of the furnace, and extending into and substantially half-way across the bridgewall, one of said flues opening into the atmosphere near the top of the combustionchamber, and extending in one side Wall bridge-wall downwardlyin convolutions; the bridge-wall portion of its last convolution eX- tendng substantially across the bridge-Wall and openin g into the furnace below the gratebars through a series ofopenings, and the other of said flues opening at one end into the atmosphere lower down than the one pre- Viously mentioned, and @Xt-ending in convolutions upwardly; the bridge-Wall portion of the last convolution extending substantially across the bridge-wall and opening into the furnace above said grate-bar through a [nultiplicity of openings in said bridge-wall, for the purposes specified.

4. In a smoke-consumer, a convoluted flue lying in one side wall and substantially half- Way across the bridge -wall of the furnace,

ceases said flue opening at one end into the atmosphere, and being extended across the bridgewall, its other end opening through a multiplicity of ports into said furnace above the grate-bars and an inwardly-projecting flange on top of the bridge-wall of said furnace,above said ports, for the purpose specified.

5. In a smoke-consumer, dues-lying Within the side walls of a furnace and extending into and along the bridge-Wall, so as to occupy each substantially one-half of said bridge- Wall, said flues opening at one end into the furnace respectively above andl below the grate, and the other end of each flue opening into the atmosphere, for the purposes specied.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
